Bill Gates and Warren Buffett want to build a new kind of nuclear reactor to generate electricity. Why? Because the wind doesn’t always blow and the sun doesn’t always shine. They intend to plunk their new toy down in the state of Wyoming on the former site of a coal-fired generating plant.

“This is our fastest and clearest course to becoming carbon negative,” says Wyoming’s governor Mark Gordon. “Nuclear power is clearly a part of my all-of-the-above strategy for energy.” Wyoming is the top coal producing state in America.

According to The Guardian, the new facility will be a joint venture between TerraPower, founded by Gates 15 years ago, and PacifiCorp, a Berkshire Hathaway-owned utility that serves customers in Wyoming, Idaho, Utah, California, Oregon, and Washington.

Small advanced reactors, which run on different fuels than traditional reactors, are regarded by some as a critical carbon-free technology that can supplement intermittent power sources like wind and solar as states strive to cut emissions that cause climate change. “We think Natrium will be a game-changer for the energy industry,” Gates told a media conference in Cheyenne, Wyoming this week.

345 Megawatts

The Guardian says the new generating station will produce 345 megawatts of electricity, but the output can be boosted by a molten salt energy storage component to 500 megawatts. The primary feature of the so-called Natrium technology is that it uses sodium to cool the reactor instead of water. Natrium is the Latin word for sodium, which is why its symbol on the periodic table of elements is Na.

Chris Levesque, TerraPower CEO, told the press this week the demonstration plant will cost about $1 billion and will take about seven years to build. “We need this kind of clean energy on the grid in the 2030s,” he told reporters. Actually, Chris, we need clean energy on the grid now, not 7+ years from now. A billion dollars would buy more than 500 MW of power and have it online, together with grid storage batteries, in a lot less time. Why wait?

Natrium Technology

I am not a nuclear engineer nor am I a rocket scientist, so I have to rely on Wikipedia to inform me about some things (I contribute $5 a month to support Wikipedia and encourage you to do the same).

Here is what I found out:

Advantages

The primary advantage of liquid metal coolants, such as liquid sodium, is that metal atoms are weak neutron moderators. Water is a much stronger neutron moderator because the hydrogen atoms found in water are much lighter than metal atoms, and therefore neutrons lose more energy in collisions with hydrogen atoms.

This makes it difficult to use water as a coolant for a fast reactor because the water tends to slow (moderate) the fast neutrons into thermal neutrons (though concepts for reduced moderation water reactors exist).

Another advantage of liquid sodium coolant is that sodium melts at 371K and boils / vaporizes at 1156K, a total temperature range of 785K between solid / frozen and gas / vapor states. By comparison, the liquid temperature range of water (between ice and gas) is just 100K at normal, sea-level atmospheric pressure conditions. Despite sodium’s low specific heat (as compared to water), this enables the absorption of significant heat in the liquid phase, even allowing for safety margins. Moreover, the high thermal conductivity of sodium effectively creates a reservoir of heat capacity which provides thermal inertia against overheating.

Sodium also need not be pressurized since its boiling point is much higher than the reactor’s operating temperature, and sodium does not corrode steel reactor parts.[2] The high temperatures reached by the coolant (the Phénix reactor outlet temperature was 560° C) permit a higher thermodynamic efficiency than in water-cooled reactors. The molten sodium, being electrically conductive, can also be pumped by electromagnetic pumps.

Disadvantages

A disadvantage of sodium is its chemical reactivity, which requires special precautions to prevent and suppress fires. If sodium comes into contact with water it reacts to produce sodium hydroxide and hydrogen, and the hydrogen burns when in contact with air.

This was the case at the Monju Nuclear Power Plant in a 1995 accident. In addition, neutron capture causes it to become radioactive; however, activated sodium has a half-life of only 15 hours. Another problem is sodium leaks which are regarded by a critic of fast reactors, M.V. Ramana, as “pretty much impossible to prevent.”

Fuel Used

Wikipedia adds that a natrium facility that generates less than 500 MW of electricity uses “uranium-plutonium-minor-actinide-zirconium metal alloy fuel, which is supported by a fuel cycle based on pyrometallurgical reprocessing in facilities integrated with the reactor.” I don’t know about you, but the words “uranium” and “plutonium” don’t sound like “different fuels compared to traditional nuclear reactors.”

The Guardian points out that nuclear power experts have warned that advanced reactors could have higher risks than conventional ones. Fuel for many advanced reactors would have to be enriched at a much higher rate than conventional fuel, meaning the fuel supply chain could be an attractive target for militants looking to create a crude nuclear weapon. And don’t even be concerned about Russian hackers. We know those malefactors only like to interrupt gasoline pipelines and beef processing plants. Pooty Poot and his henchmen would never stoop so low as to hack a nuclear power plant…would they?

People always rush to criticize Tesla for selling emissions credits, but no one wants to talk about the $80 million the US Department of Energy has already invested in TerraPower with millions more coming in the future. No one would expect Bill Gates and Warren Buffett — two of the richest white men in history — to foot the bill for their boondoggles all by themselves, would they?

All Of The Above

The key to understanding this story is found in Governor Gordon’s use of the words “all of the above.” That’s free market speak for “We’re happy to have a piddly little 350 MW facility of over here, just so long as we can continue supporting coal- and gas-powered generating plants that churn out hundreds of gigawatts over there.” In other words, it’s a smokescreen designed to allow fossil fuel interests to kick the can down the road a little further and add some greenwashing to their corporate portfolios at the same time.

Being rich does not necessarily make a person all that smart. America needs more nuclear power like a fish needs a bicycle. People in Wyoming may be fooled by this blather, but CleanTechnica readers aren’t taking the bait. Natrium was probably selected as the name of thus new nuclear technology because it sounds a little like “nature” or “natural.” That’s a great marketing ploy, but we’re not buying it. Frankly, the Bill and Warren show is more than a little disappointing.

BYD is offering free car insurance on select EVs in new end-of-year sales promo

China’s EV leader wants to close the year strong with a new sales promotion. BYD is now offering free car insurance on certain EVs ahead of the upcoming Chinese New Year. Will it be enough to take the global EV sales crown in 2024?

BYD offers free insurance on some EVs to boost sales

With a record 506,804 NEVs (EV and PHEV models) sold in November, BYD has now had two straight months with over 500,000 in vehicle sales.

The EV giant has no plans to slow down. On Thursday, BYD announced its latest “New Year GO New Car” sales promotion on its Weibo page.

From today, December 26, 2024, through January 26, 2025, BYD is offering free car insurance on select PHEVs and EVs in its Ocean and Dynasy lineups. The promo includes several top-selling EVs, including the Dolphin, Seal, and Sea Lion 07.

Through the first 11 months of 2024, BYD sold nearly 3.76 million NEVs, including 1.56 million all-electric models. The promo comes as BYD is in a tight race with Tesla for the global EV sales crown for 2024.

Through September, Tesla delivered 1.3 million EVs compared to BYD’s 1.17 million. Since Tesla doesn’t report monthly sales numbers, we will have to wait until the end-of-year numbers come out to determine who will take the EV sales crown in 2024.

The Seagull EV, BYD’s cheapest electric car starting under $10,000, was once again China’s best-selling vehicle last month after topping the Tesla Model Y. BYD sold 56,156 Seagull EVs last month alone in China.

Although the global EV sales race between BYD and Tesla is heating up into the end of the year, the Chinese EV leader is quickly outselling some of the largest global automakers.

BYD sold more vehicles globally than Nissan and Honda in the third quarter, and it is now closing in on Ford.

The rate at which China has rebuilt its car industry is truly staggering

The rate at which China has rebuilt its car industry is truly staggering

After starting off slow, China’s EV industry has reorganized itself in record time, going from a global laggard to a global leader in about 5 years – showing other countries how it ought to be done.

In 2020, China was still early in its EV transition, lagging behind many other countries and regions. With EVs only consisting of 5.4% of the country’s car market, it lagged behind California and almost all of Europe – even the slower-adopting countries, like Romania. It was only barely ahead of the 4.6% global average that year.

It set a relatively unambitious goal of 50% EV sales by 2035 – and those 50% didn’t even need to be gasoline-free, they could be hybrids or plug-in hybrids which still have a gas engine inside (what China classifies as “New Energy Vehicles” or NEVs). Around that time, both California and Europe were thinking about banning gas car sales by 2035 – and each of those targets probably could have been earlier, too.

Now, with 2025 coming in just a week, China is likely to hit that 2035 target ten years early – closer to the year that it set the target than the year that the target was set for. It even moved its target forward to 45% NEVs by 2027 this January… and exceeded that target within less than a year.

It’s an indication of how much China is able to do when they put their minds to it – and how other countries have completely failed to keep up due to bickering and resistance from companies or governments being hostile to better technology.

The rapid rise in Chinese EVs

2020 was a turning point for the Chinese EV industry. China responded strongly to the start of the COVID-19 pandemic (and as a result, had a lower death rate than almost any country, despite life within China being relatively normal after initial lockdowns), which meant a large drop in vehicle sales in the country (much like the rest of the world).

But when sales recovered, China’s eyes had turned inwards. Not only had domestic EV makers started to ramp up production rates and quality (after a decade of smart industrial policy focusing on mineral supply and encouraging domestic manufacturers), but the rest of the world had spent years blaming China for all sorts of ills (like carbon emissions, which China was criticized for not doing enough about, and now is criticized for doing too much). Technology blockades and discussions about tariffs led to consumer nationalism, with Chinese consumers expressing interest in domestic goods more than they had before.

This, coupled with new emissions rules that the rest of the world’s automakers hadn’t prepared properly for (despite having 7 years notice) led to a glut in gas car supply – mostly from foreign brands – which we called the “canary in the coal mine” for where the global ICE car market was going.

Chinese auto dealers could have responded to this by asking the government to reverse the rules, but instead they asked for (and were granted) a six month amnesty in order to clear unsold cars off of their lots, and otherwise demanded that auto manufacturers shape up and build EVs faster.

As a result of this mentality, China became the top global exporter of automobiles this year – a title that Japan had for decades.

Meanwhile, the West drags its feet

It’s a stark difference to how automakers and governments usually behave in the West (and in Japan), working to slow down transitions and add protectionist measures instead of gearing up for an inevitable change in the industry that already started.

And the regressive portions of Western governments are all too happy to oblige, with for example the US republicans promising to hold the US auto industry back even further, ensuring it isn’t ready for the present, and their far-right ilk in European governments arguing for similar measures.

President Biden’s administration did do its part to try to turn US industrial policy around to be ready for EVs with the excellent Inflation Reduction Act, which brought hundreds of billions in investment and hundreds of thousands of EV jobs to the US. Biden’s EPA and DOT also improved several emissions rules (despite softening them somewhat after industry pressure) to move the industry forward. But it also implemented large tariffs, which could help to breed complacency.

But unfortunately for America, the next occupant of the White House is convicted felon Donald Trump, who finally received more votes than his opponent on his third attempt (despite committing treason in 2021, for which there is a clear legal remedy), with less than half of the country voting to ensure that US manufacturing fall further behind.

In his last stint squatting in the White House, the EPA knowingly worked against clean air and instead of preparing the US to lead the EV transition, it focused on petty losing squabbles with states that are actually trying to move the US forward. We could have had smarter industrial policy, like China, but instead government worked to shatter the regulatory certainty that President Obama had helped to lay out.

Luckily, most Western auto manufacturers may have learned their lessons, and this time they’re finally asking government not to blow up emissions rules. They recently donated money to the famous narcissist, presumably hoping to get in his ear – we’ll have to wait and see whether what they say is actually geared towards the future (and whether the ignoramus they’re saying it to is even able to comprehend it). Though that could all be for naught, because one of Mr. Trump’s closest allies is Elon Musk, CEO of the largest EV maker in the US, who has confusingly focused his advocacy on harming EVs.

Change is coming faster than you think

China’s rapid rise in EV sales, meeting targets well ahead of schedule, may seem anomalous at first blush. It’s not often that a target gets met in one third of the time allotted for it, especially when you’re dealing with a country of 1.5 billion people. That’s a lot of inertia to turn around.

But there are other examples of targets getting met and exceeded early, and companies and governments need to be aware of these and maintain flexibility instead of fighting in the face of positive change.

Norway is one example, where the country was already far ahead of the international community, and set a target to end gas car sales by 2025. While there are still a trickle of non-EVs sold in the country, Norway’s market was already over 90% electrified in 2021.

This is not uncommon with technology adoption curves, as once a technology reaches a critical mass, most consumers consider it the default and will switch to it without much issue. That critical mass has already been met in most Northern European countries and in China, but other places could get there fast.

Once they do, who do you think will come out for the better – the countries and companies whose manufacturing base is ready to supply products that fuel that change, or the ones that have spent decades bickering and trying to slow it down so they can continue spewing poison in all of our lungs?

And as I’ve ended several articles in recent years: we should have been doing more earlier, but as the famous (possibly Chinese) proverb says, “the best time to plant a tree is 20 years ago, the second best time is today.”

Kia's new Syros SUV is going electric as a low-cost Hyundai Inster EV twin

Kia introduced its new Syros SUV last week. Although it was launched with a gas-powered engine, Kia plans to launch the all-electric version soon. The new Kia Syros EV will share underpinnings with the Hyundai Inster EV as its latest low-cost electric model.

What we know about the upcoming Kia Syros EV

India’s EV market is expected to surge over the next few years. In 2024, the India EV market is projected to be valued at around $24 billion. That number is expected to reach nearly $118 billion by 2032.

Kia is looking to take advantage of the transition. After launching its first vehicle (Seltos) in India in 2019, Kia is already one of the top 10 auto manufacturers in the region.

The Korean auto giant has added several models to its lineup, including the Sonet, Carnival, Caren, and electric EV6 and EV9 SUVs.

Just last week, the Kia Syros made its global debut. Kia calls the compact SUV “revolutionary,” but there’s one problem: it only has two gas-powered engine options. That will soon change. According to Autocar India, Kia will launch the Syros EV in India in early 2025.

Although no other details were confirmed, the Kia Syros EV will share its K1 platform with the Hyundai Inster EV. Hyundai’s compact electric crossover has two battery options, 42 kWh and 49 kWh, good for 300 km (186 mi) to 355 km (220 mi) range on the WLTP cycle.

In Europe, the Inster EV starts at around $30,000. In Korea, the electric crossover is known as the Casper Electric, and prices, including incentives, start around $20,000.

Kia’s new electric SUV is expected to start in the price range of Rs 15 lakh-20 lakh (ex-showroom), or around $17,500 to $23,500.

Despite the difference in powertrain, the electric version is expected to have the same styling and features as the gas-powered models. Kia expects between 50,000 and 60,000 in sales between the upcoming electric Carens and Syros EV models by 2026.

The company is launching a series of more affordable, mass-market EVs globally, including the EV3, EV4, and EV5, to secure its spot in the industry as it shifts to electric vehicles.
